Vojtkó, András: Relationships between the morphology of the spores of Hungarian Hepaticae species and their strategy types

and JÁRAI-KOMLÓDI 1975, BlSCHLER 1982, BOROS et al. 1993, VOJTKÓ 1993). There are only Hungarian Hepaticae in the investigations. The species of each life strategy type were characterized according to the 4 morphological features which are thought to be the most important: - size (spore size): it is the most important factor of dispersal and distribution. The size range consists of 10 observed values which include the smallest and the biggest representations of the species. - form (the type of the spore): it has mainly taxonomic and evolutionary importance. - the thickness of the spore wall: it determines the life span and viability of the spore. It is mainly necessary for separating the species of the short life shuttle (SL) and the long-lived (perennial) shuttle (LS) strategy types. The spore wall of mosses is often very thin and simple except for Hepaticae species which have very complicated structure and it can be hardly described, opposite to mosses. - ornamentation: this feature gives the variability of bryophytes. Together with form this feature has also mainly taxonomic importance. But if we take into account that the species from the same family are in the same strategy types then it is usually quite informative, too. Sometimes the spore wall is almost smooth but in most cases it is changing and more or less determined with visible ornamentation. RESULTS AND DISCUSSION Colonist: C Examined species/All the Hungarian species: 23/89 (25.8%). Size range: 7-29 |im. Spores are mainly of globose type with 0.7-2jim thin spore wall. The ornamentation is light pilum or gemma (Table 1). Annual shuttle: AS Examined species/All the Hungarian species: 8/10 (80%) Size range: 40-75 [im. Subtriangulare spores, the spore wall is 1-5 |nm thin. The ornamentation is quite complicated and very difficult to describe. The surface is reticulate (Table 2). Long-lived (perennial) shuttle: LS Examined species/All the Hungarian species: 2/11 (18.2%) Size range: 25-30 |lm. Spores are of globose type. The spore wall 1-2 |im thin, its ornamentation is small bacule (Table 3).
